4 / 14 page CAT5271, CAT5273 http://onsemi.com 4 Table 4. CAPACITANCE TA = 25C, f = 1.0 MHz, VDD = 5 V Symbol Test Conditions Max Units CI/O (Note 11) Input/Output Capacitance (SDA, SCL) VI/O = 0 V 8 pF Table 5. POWER UP TIMING (Notes 11 and 12) Symbol Parameter Max Units tPUR Power-up to Read Operation 1 ms tPUW Power-up to Write Operation 1 ms 11. This parameter is tested initially and after a design or process change that affects the parameter. 12.tPUR and t PUW are delays required from the time VCC is stable until the specified operation can be initiated. Table 6. DIGITAL POTENTIOMETER TIMING Symbol Parameter Min Max Units tWRPO Wiper Response Time After Power Supply Stable 50 ms tWR Wiper Response Time: SCL falling edge after last bit of wiper position data byte to wiper change 20 ms Table 7. A.C. CHARACTERISTICS VDD = +2.7 V to +5.5 V, −40C to +85C unless otherwise specified.
